[Sam is outside the bar's front door, cleaning graffiti off the wall, namely the initials N.R.P. Cliff is watching him through the door's window]

Rebecca Howe:
Not again.

Sam Malone:
It's the fifth time this week. If I find out who this N.R.P. creep is, I'm going to really let him have it.

[inside the bar, Norm is pilfering beer out of the beer taps]

Cliff Clavin:
Hurry up Norm, Sam is getting a lot faster at this.

Norm Peterson:
Got it.

Cliff Clavin:
Hey Norm. I know that the N.P. stands for Norm Peterson. What does the R stand for?

Norm Peterson:
Resourceful.
